IMPROVEMENT IN PEGGlNG-MACHINES.

Specification forming part of Letters Patent No. 211,651, dated January 28, 1879; application filed September 21, 1878.

To all whom it may concern:

Be it known that I, J OSEPH E. CRIsP, of Boston, in the county of Suffolk, in the Commonwealth of Massachusetts, have invented an Improvement in Pegging Machines, of which the following is a specification:

This invention has for its object the following described mechanism for driving pegs, whereby, by the impulse of one blow, or by the descent of the driving-bar, an awl is driven and withdrawn, the peg-strip fed, and a peg severed and driven.

In the drawings, Figure 1 is a perspective View of my machine, showing the relation of the strip-case to the feeding and driving mechanism. Fig. 2 is a vertical central section of my device. Fig. 3 is a vertical central section at right angles to the section shown in Fig. 2. Fig. 4 represents the device employed in feeding the peg-strip. Fig. 5 is a detail view.

Heretofore it has been common in peggingmachines to feed the peg strip, sever a peg, drive and withdraw the awl, and drive a peg by one stroke of the driving-bar. It has also been common to feed a peg-strip, sever a peg by the upward movement of the driving-bar, drive and withdraw the awl, and to drive the peg at the next downward stroke of the driver. Pegging-machines have also been made which employ a revolving barrel for feeding cut pegs to the driver. The awls haveinvariably been made in one piece.

My invention consists, first, in mechanism for driving an awl, made in two longitudinal parts, counterparts of each other, withdrawing the awl, feeding the peg-strip, cutting the peg, and driving a peg into the puncture made by the awl with one impulse of the bar carrying the driver 5 secondly, in an awl made in two equal longitudinal parts, with mechanism for closing or holding the parts together while descending, and for opening the same to permit of the passage of a peg between when withdrawn, whereby the inner surface of the divided awl becomes two walls or sides of the driveway for the distance of their length, as will hereinafter be more fully described thirdly, in severing a peg and conducting it to a recess on the side of the passage where it is de posited by the descent of the driver, while the preceding peg is being driven by the continued descent of the driver, and from whence it is automatically fed into the driveway upon the upward movement of the driver.

The peg-wood J preferably is coiled within the case J, from whence it is fed through the feedway in the arm or bracket K, which projects from the barrel A, to support the pegstrip holder or case J, by means of the hooks g, which lay hold of the sides of the peg-strip. These hooks are attached to the sliding plate G, which is itself operated by the cam-groove F in the'cam F, and the cam is driven by the descent of the awl-drivin g bar E.

To hold the end of the peg-strip firmly against the side of the driving-rod H, which forms the end of the feedway, and against which the end of the peg strip abuts after it is fed and while it is being cut, and also to prevent the peg-strip from being thrown back by the outward movement of the hooks g, which, although rounded upon their outer end, yet necessarily exert a slight outward force upon the peg-strip as they move outward preparatory to again feeding, the bar I is arranged within the feedway near the top thereof in such a way that the notches or teeth m upon one end and its opposite end, m, rest upon the top of the peg-strip. This bar I. is held in position by the link i, which is pivoted to the top of the bracket K, and to the bar I,

near its center, projecting downwardly and inwardly from the top of the fecdway to the bar, whereby the bar can be lifted only by an inward movement thereof, an outward movement upon it tending to throw the notches or teeth into the top of the peg-strip.

The spring m acts to steady the bar I in its duty. The under side of the bar is recessed from the teeth or notches m to near the opposite end of the bar m. The inner end of the bar m rests upon the top edge of the pegwood, and holds it firmly in position in the feed-way, so that pegs may be cut to the full length of the strip, the pressure upon the top of the peg-wood supporting the end of a piece of peg-wood while a peg is being out therefrom, which otherwise might become canted or turned in the driveway and clog the machine.

the peg-strip while the hooksare being movedv outwardly, and that the peg is cut by the downward movement of the driving-bar H.

The awl-driving bar E is operated by means of the latch D, which is pivoted near the lower end of the arm D in such a way that its lower end, when forced inwardly by the action of the spring d, shuts upon the awl-driving bar E, and contacts with the shoulder or step E. The downward movement of the awl driving bar E continues until the latch is tripped by the portion 01 impinging against the inclined surface (1 upon the upper inner corner of the barrel A. The bar E in its descent, by means of the projection e, operates the cam-F, and throws the same into the path of the downwardly-projecting arm D. This arm D continues to move downwardly after the bar E has ceased to fall by the tripping of the latch D, and contacts with the end of cam 1*, which has been thrown into its path, as above said, and by its continued descent moves the cam back to its original position, and thus causes the edge of the cam which contacts with the projection E to lift the awldriving bar E and to move outwardly the reciprocatin g plate J.

Pivoted to the awl-supporting bar E, at its lower end, are the swinging connectingbars E, each of which carries at its lower inner end one-half of the divided aw1E preferably secured therein by means of dovetailed projections upon each side of the two parts of the awl at the top, which fit into corresponding recesses at the inner lower end of said connecting-bars.

These connecting-bars E play in guides E in the nozzle B, and each portion of the divided awl is so shaped and secured to these connecting-bars that they converge at their ends to form the point, except when separated by the descent of the peg as it is driven and it will be observed that the upper inner corner of each section of the awl is somewhat rounded or inclined in order that the interior of the driveway may be continuous and without obstruction and it will be observed that the speed, length, and incline of each section of the awl is so proportioned to the speed and position of the driver that upon the withdrawal of the end of the awl from the puncture the driver immediately commences to spread the two parts of the awl by contacting or causing the peg to-come in contact with the inclines.

The spring-guides E serve to prevent the pivoted connecting-bars from being thrown out any farther than is necessary to secure a passage for the peg between them in its downward movement, and also to center the two parts of the awl as it is being driven, in order that the points may be brought together and held firmly in that position while they are be: ing presented to the work. ,i'

The end of the nozzle is preferably provided with short projections b for assisting in firmly holding the pegger upon the work when in operation.

The shoulder 71/ on the driving-bar serves to lay hold of and carry the severed peg from the peg-strip to the pocket or recess k upon the arm 70, where it remains until the drivingbar is lifted, when the action of the spring is throws the peg from the chamber into the path of the driver at W.

Upon the side of the nozzle is formed a recess, B, into which fits a pivoted arm, k provided with a groove, which forms one side of the driveway of the nozzle. This arm acts in opposition to the spring 70; and it will be noticed that the groove in this arm, whichforms a portion of the feedway, inclines some. what inwardly to the point H, where a recess is formed of sufficient depth to receive the peg which is forced therein after it is cut, and which remains undriven until the nextdescent of the driver. I

The driverH carries the knife h, which may. be suitably attached thereto, and which severs.

from the peg-strip a peg of the desired width upon the descent of the driver.

A stop, h, is located just above the point. where the peg-stri p is fed into the driveway, so that the knife plays between it and the wall of the chamber in its descent, and the cut peg is prevented from being drawn upward by the,

upward movement of the driving-bar.

The cross-head 0 acts in opposition to the spiral spring M, which is confined within the cylinders N N, the cylinder N sliding within.

way enters it lies in the awl-driving bar E, which forms three sides of the upper por-,

tion thereof, the grooved inner side of the bracket 70 and arm 70 forming the fourth side. The lower portion of the driveway is between the inner surface of the connecting-bars E and v the opposing walls of the awl and the sides of the nozzle; and it will be observed that the lines of division of the various parts of these devices forming the driveway are so ar ranged as to be in line with the center of the In some. mstances, to, prevent undue wear of the working parts, the awl. may be so arranged in relation to its operating mechanism and the end of the nozzle that its point will and is driven by the third descent.

I do not confine myself to this particular opcontact, or rest upon, or nearly touch the material before it is driven, in orderthat there maybe no recoil caused by the quick uninter rupted descent ofthe awl being suddenly broken by entering the material. 7

The operation of this; device is as. follows: The peg-strip being presented to the feeding mechanism is seized by the automatically-reciprocatin g feeding-hooks, which draw the peg-strip through the feedway until the end of the strip abuts against the side of the drivin gbar below the shoulder ]L2. The notches or teeth on bar I prevent-the'strip from receding. Upon the descent of the driver or plunger a peg is cut from the end of the'p eg-strip, and the {peg previously cut. deposited in a pocket or recess. conveniently arranged midway between the point where-the pegstrip is cut and the end of the nozzle The same impulse that causes a peg to be severed and one to be deposited in the pocket. also servesto drive the awl into the material to be pegged, to withdraw the same, and to causea peg previously deposited in the pocket, and from which it has been expelled into the pathway. of the driver, to. be driven.

It will be seen that the awl consists of two duplicate parts, which, when supported upon the connecting-bars E substantially as shown, converge at their points in driving.

It will be observed that the peg which is severed by the first descent of the driver is deposited by the next descent in the pocket Of course eration by which the peg is fedforward, as the same may be severed from the strip and deposited in the pocket by one descent of the driver with a slight modification of the mechanism.

It will also be observed that upon the descent of the end of the driver carrying the peg which has been deposited in the driveway from the pocket before it that'a very slight inipulse serves to spread the two parts of the awl apart, causing the opposing sides of each part of the awl to become the sides of the driveway through which the peg passes.

It will be observed, further, that by the principle shown in this device of cutting a peg and carrying it a portion of the way to the foot of the nozzle to be driven by the next descent of the driver, a very long slim noz-- zle may be employed, and a comparatively small throw given the driver. This construction is of great importance, as it enables the nozzle to be introduced, and therefore a peg to be driven in places inaccessible to the ordinary short-nosed pegger. By coiling the pegwood within the casea much larger quantity can be fed continuouslythan with the ordinary pegger using uncoiled stiips,

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States---- 1.
